Let's divide 18551 by 87
We're looking to find how many times 87 goes into 18551.

Step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 87

Advancing to step 2:
18 divided by 87 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 87

Step 3:
87 goes into 185 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 174 from 185 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 87

Let's proceed to step 4:
When dividing 115 by 87, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 28 after subtracting 87 from 115.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 87

Step 5:
87 can be fit into 281 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we subtract 261 from 281, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 6:
87 goes into 200 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 213.2
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
87 can be fit into 260 2 times, resulting in a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 213.22
Deduct 174 from 260 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 213.22, with a leftover of 0.086.
